I have a problem with my Peugeot 306 deasel pump its not idling
the diesel tank capacity for a 2001 306 Hdi is approx £80 so around 55litres
Four
under the steering wheel
4 quarts
Correct coolant level for the 306 is about 4 inches below the top of the radiator. If it is filled any higher the car will blow out the excess DO NOT OVERFILL
The 306 is a better option but neither will go straight in as the power steering pump will want to be where the radiator is.
Phase 1 and 2 = 1.9 Turbo Diesel Phase 3 = 2.0 HDI Turbo Diesel

A Peugeot 306 that has a noisy fan and overheating may need a fan replacement. One may also look into the coolant or thermostat to resolve the issue.
